Quantum tunnelling for Hawking radiation from a dynamical Black Hole

Understand

The paper deals with Hawking radiation related to non-static spherically symmetric black hole.

• Quantum corrections are incorporated using Hamilton-Jacobi method beyond semi-classical approximation.
• It is found that different order correction terms satisfy identical differential equation as the semiclassical action and are solved by a typical technique.
• It has been shown that with proper choice of the proportionality factors, one loop back reaction effect in the space time can be obtained.
